상기와 같이 구성된 본 발명의 작용을 설명하면 다음과 같다.Referring to the operation of the present invention configured as described above are as follows.

스텝모타(SM)에 구동에 의해 그 축단에 축설된 스포로킷(1)구동되고, 상기 스포로킷(1)에 결착된 체인(2)은 하부로울러(R0-L)에 축단에 축설된 스포로킷(3)에 결착되어 하부로울러(R0-L)가 구동됨과 동시에 상기 하부로울러(RO-L)와 맞물려 있는 상부로울러(RO-U)구동된다.The sprocket (1) built in its shaft end is driven by the drive of the step motor (SM), and the chain (2) fixed to the sprocket (1) is built in the shaft end in the lower roller (R0-L). The lower roller R0-L is driven by being attached to the sprocket 3, and the upper roller RO-U engaged with the lower roller RO-L is driven at the same time.

상기 상, 하부 로울러에 의해 라미네이터에서 코팅된 필름(LF)은 화살표(↑)방향으로 이동된다.The film LF coated on the laminator by the upper and lower rollers is moved in the direction of an arrow ↑.

이때 라미네이터(도시생략)에서 코팅된 필름(LF)의 공급량이 많으면 " ㄷ"형의 가이드봉(4)이 B-3에 위치하고 필름 공급량이 적을 경우에는 필름의 장력이 가해지므로서 공급량 부족 정도에 따른 가이드봉(4)의 위치가 변화되는 것으로서, B-2, B-1에 위치하게 된다. 참고적으로 B-0, B-1, B-2 각각의 변위각도는 30°이다.At this time, if the supply amount of the film (LF) coated by the laminator (not shown) is large, the "c" type guide rod 4 is located in B-3, and if the film supply amount is small, the tension of the film is applied and the supply amount is insufficient. As the position of the guide rod 4 according to the change, it is located in B-2, B-1. For reference, the displacement angles of B-0, B-1, and B-2 are 30 °.

한편 가이드봉(4) 상부 일측단에 형성된 광차단편(L)이 3개(L-0, L-1, L-2)로 각각 위치하며, 이때에도 30° 각도의 차이가 있고, 가이드봉(4)이 B-0에 위치하면 광차단편(L-0)에 의하여 광차단기(PI-0)의 빛이 차단되며, 가이드봉(4)이 B-1에 위치하면 광차단편(L-1)에 의하여 광차단기(PI-1)의 빛이 차단되며, 가이드봉(4)이 B-2에 위치하면 광차단편(L-2)에 의하여 광차단기(PI-2)의 빛이 차단된다.(도1참조)On the other hand, the light blocking pieces (L) formed at one end of the upper part of the guide rod (4) are located in three (L-0, L-1, L-2), respectively, and at this time there is a difference of 30 ° angle, When 4) is located at B-0, the light of the optical breaker (PI-0) is blocked by the light blocking piece (L-0), and when the guide rod 4 is located at B-1, the light blocking piece (L-1) By the light of the light blocker (PI-1) is blocked, when the guide rod (4) is located in B-2 is blocked by the light blocker (L-2) light of the light blocker (PI-2). See Figure 1)

광차단기(PI-0)의 빛이 차단되면 포토 다이오드와 포토트란지스터 사이의 빛이 차단되므로 PI-0의 콜렉터 핀4의 전압은 H(HIGH)로 되고, 이는 커넥터 CN1의 핀2을 거쳐 트란지스터 Q26의 베이스 전압이 H로 되고 이의 콜렉터 전압은 L로되어 마이크로프로세서 직접회로U5의 핀5는 L이 걸리게되어 0 볼트가 된다.When the light of the light breaker (PI-0) is cut off, the light between the photodiode and the phototransistor is cut off, so the voltage of collector pin 4 of PI-0 becomes H (HIGH), which is passed through pin 2 of connector CN1. The base voltage of jistor Q26 goes to H, and its collector voltage goes to L, so pin 5 of microprocessor integrated circuit U5 takes L to zero volts.

만일 광차단기 PI-1의 빛이 차단될 경우 마찬가지로 PI-1의 콜렉터는 H, 커넥터 CN1을 거쳐 트란지스터 Q27의 베이스는 H, 콜렉터는 L이 되어 트란지스터 Q26의 콜렉터 전압을 저항 R24, 와 R25에 의해 분할된 전압이 걸리며, 이때의 전압은 0.5V가 되며, 이는 U5의 핀5에 가해지고If the light of the light interrupter PI-1 is cut off, the collector of PI-1 goes through H, the connector CN1, the base of transistor Q27 becomes H, and the collector becomes L, so that the collector voltage of transistor Q26 is resistance R24, and R25. Takes the voltage divided by, and the voltage is 0.5V, which is applied to pin 5 of U5

마찬가지로 광차단기 PI-2의 빛이 차단되면 같은 경로에 의해 트란지스터 Q26의 콜렉터 전압은 저항 R24가 R25+R26에 의해 분할된 전압이 걸리므로 직접회로 U5의 핀5에는 1V의 전압이 걸리게 된다.(도 2 참조)Likewise, when the light of the light interrupter PI-2 is blocked, the collector voltage of the transistor Q26 is divided by the resistor R24 by R25 + R26 by the same path, so that the voltage of pin 5 of the integrated circuit U5 is 1V. (See Figure 2)

한편 도 1에 도시된 바와 같이 코팅된 필름(FL)이 필름슬라이드바(FILM SLIDE BAR)(4)에 있어서, (4)의 위치가 B-3일 경우엔 3개의 광차단기 PI-O, PI-1, PI-2의 어떤 것에도 빛이 차단되지 않으므로 트란지스터Q26의 콜렉터 전압은 5V가 되어 직접회로 U5의 핀5에는 5V가 인가된다.Meanwhile, as shown in FIG. 1, the coated film FL has a film slide bar 4 in the film slide bar 4, in the case where the position of 4 is B-3, three light-blockers PI-O and PI are used. Since no light is blocked at any of -1, PI-2, the collector voltage of transistor Q26 is 5V, and 5V is applied to pin 5 of integrated circuit U5.

다시말해 필름슬라이드바(4)의 위치는 필름의 여유가 가장 많을 경우 B-3위치가 되며, 이때엔 5V가 인가되고, 필름의 여유가 전혀 없을 경우 B-0의 위치에서 OV가 인가되며, 필름슬라이드바(4)이 위치가 30°간격으로 B-2에서 1V가 인가되고, B-1에서는 0.5V의 전압이 발생되어 직접회로 U5의 핀5에 인가된다.In other words, the position of the film slide bar (4) is the B-3 position when the film has the most margin, at this time 5V is applied, when there is no margin of the film is applied OV at the position of B-0, The film slide bar 4 is applied at 1V at B-2 at a 30 ° interval, and a voltage of 0.5V is generated at B-1 and applied to pin 5 of the integrated circuit U5.

한편 마이크로프로세서(U5)의 직접회로U5의 핀5에 입력되는 전압에 의해 5V가 인가되면 외부에서 가변설정속도에 의하여 400∼1200PPS(PULSE PER SECOND)의 주파수가 발생하며, 1V에는 350PPS, 0.5V에는 300PPS, 0V에는 0PPS의 주파수를 생성하여 U5의 핀37, 38, 39, 40에 서로 위상이 다른 4종류의 펄스신호 A, NA, B, NB를 발생하며, 그 파형을 도3에 도시된 바와 같다.On the other hand, when 5V is applied by the voltage input to pin 5 of the integrated circuit U5 of the microprocessor U5, the frequency of 400 ~ 1200PPS (PULSE PER SECOND) is generated by the variable set speed externally, and 350PPS, 0.5V at 1V. It generates 300PPS and 0V at 0V, and generates four kinds of pulse signals A, NA, B, and NB which are out of phase with each other on pins 37, 38, 39, and 40 of U5, and the waveform is shown in FIG. As shown.

신호 A는 트란지스터 Q11에서 파형정형 및 전치증폭되고 Q1에서 전력증폭되고, 신호 NA는 Q13 및 Q12에서 증폭되며, 신호B는 Q15 및 Q14에서 증폭되고, 신호 NB는 Q17 및 Q16에서 증폭되어 커넥터 CN5로 거쳐 스텝모타(SM)을 구동시키게 된다.Signal A is waveform shaped and preamplified at transistor Q11, power amplified at Q1, signal NA is amplified at Q13 and Q12, signal B is amplified at Q15 and Q14, signal NB is amplified at Q17 and Q16, and connector CN5 Then, the step motor SM is driven.

스텝모타(SM)은 인가되는 주파수에 의해 회전수가 가변되며, 가변설정속도에 의해 400∼1200PPS 발생시에는 회전속도가 가변되어 설정된 스피드로 정상구동을 하다가 350PPS로 회전수가 감소하고, 300PPS로 회전수가 다시 감소되며, OPPS에서 회전은 정지된다.The step motor SM rotates according to the applied frequency, and when 400 ~ 1200PPS is generated by the variable set speed, the rotation speed is variable and it is normal drive at the set speed, then the rotation speed decreases to 350PPS, and the rotation speed is changed again to 300PPS. Is decremented and rotation is stopped in OPPS.

이상에서 설명한 바와 같이 본 발명은 필름의 공급량에 의해 필름의 장력이 변화에 의해 필름슬라이드바의 위치가 변화하고 이 위치에 따라 마이크로프로세서의 직접회로에서 4종류의 신호 주파수 설정 스피드로 350PPS, 300PPS, 0PPS를 발생하고 이 신호는 위상이 서로 다른 4개신호가 되어 스텝모타(SM)의 회전속도를 변화시켜 라미네이터로 부터 공급되어 자공절단기로 인입되는 필름의 양을 일정하게 유지하는 것이다.As described above, according to the present invention, the position of the film slide bar is changed by the tension of the film by the feeding amount of the film, and according to this position, 350PPS, 300PPS, It generates 0PPS, and this signal becomes four signals having different phases, thereby changing the rotation speed of the step motor SM to maintain a constant amount of film fed from the laminator and introduced into the hole cutting machine.

또한 이렇게 하여 인입된 필름은 자동절단기에 의해 정밀하게 절단되는 효과가 있다.In addition, the film introduced in this way has an effect that is precisely cut by the automatic cutting machine.
